Description: When he was a child, Keitaro Urashima promised with a girl that they would meet in Tokyo University (Toudai). For this reason he has tried to get into the prestigious university, but has failed the entrance exam two years in a row. When his parents kick him out of the house he tries to find lodging at his Grandmother's inn, but unbeknownst to him it has been changed into an all-girls dormitory. He is allowed to stay in the position of kanrinin (dorm manager) but his clumsiness tends to land him in trouble with the girls. To achieve his dream, he studies to pass the Tokyo University exam along with Naru Narusegawa, who has her own reasons for wanting to get into Toudai.
